Sony Reader PRS-500.
I asked a question about ebook readers on a russian forum. I said that the most important issue is my eyes. I cannot read from computer screens. One guy told me that there is only one solution - Sony. It was in November 2006. Bought mine in January 2007, tooth fairy brought it to me
I am totally in love with the reader. Although I was buying it only as sunstitute for hardback books when I go on holidays, I don't read paper book since then at all.
